Keratin is an extremely strong protein that is a major component in hair, skin and nails. The majority of hair structure, about 88%, is composed of keratin. Therefore, it is important that the hair care products we use contain this naturally forming protein. Most of the keratin that comprises hair is dead matter. Hair, skin, and nails are all formed from dead cells that the body sheds as new cells push up from underneath. Regular use of Kashmir Keratin System maintains the reproduction of dead cells, which serves as an insulating layer to protect the delicate new tissue below them. This allows damaged cells to be repaired, so that hair remains healthy and resilient.
